According to his diary here on czechclimbing.com, Adam Ondra has sent Corona, 11+ UIAA (9a+, 5.15a) in Germanys Frankenjura.
Corona was established back in 2006 by Markus Bock, and at 11+ is considered to be the hardest route in the Frankenjura.
Adam needed eight tries and used different movement sequence than Marcus Bock.
Corona is on the same wall as the famous route Burn for you in Ailsbachtal. Route starts like Burn for you (Burn 4U, 11-) and after 10 moves, it comes the hardest passage about 6 moves in 8B FB without any rest. Finish consists of 15 moves at about 8b.
